With an all metal construction don't let the compact size of the Apex Accu Strike fool you. The Accu Strike was designed to handle the abuse that a sight can expect to get in the field and to provide such a durable sight for the smaller bows that are so popular on the market. The 4 fiber optic pins use extra long fibers routed through a bracket to increase durability. The low light abilities of the Accu Strike come from the glow in the dark shooter's ring, for fast target sighting, and the micro push button light that was specifically located on the Accu Strike to be more effective at lighting up the pins regardless of light conditions.
